医学命名实体识别demo:

  数据集:github.com/yixiu00001/LSTM-CRF-medical/tree/master/data_path
  实体:疾病名称/DISEASE、症状/SYMPTOM、身体部位/BODY
  模型:word2vector+bilstm+crf
  结果(130轮)测试集:精准率89.97%  召回率90.51%  F1调和90.24
                     crf loss: 2.695572
  模型:bert+bilstm+crf
  训练:bert与bilstm添加全连接,embedding:768-->120
       固定bert层,迁移上一个模型的bilstm层+全连接层参数初始化
  结果(2轮)测试集:精准率53.63%  召回率50.06%  F1调和51.78                                           
                  crf loss: 22.974451

生物化学关系抽取demo:

  数据集:非NA数据集 11k (github.com/qq547276542/Agriculture_KnowledgeGraph/)
          NA数据集 12k (维基百科匹配)
  关系类别:NA,instance of,subclass of,parent taxon
  模型:pcnn+BagAttention
  结果(35轮)测试集:非NA准确率(精准率)0.8366  total准确率0.9553 auc: 0.8987
                   前15轮 GradientDescentOptimizer(0.5)不稳定 auc: 0.8293
                   后20轮迁移参数使用AdamOptimizer(0.001)
